Update value of BeamLineConstants.ECAL_FACE

[normangraf]

The calorimeter was moved downstream for the 2019 and 2021 runs, but the value of ECAL_FACE in tracking/src/main/java/org/hps/recon/tracking/BeamlineConstants.java was not updated. This means that when comparing the track state as returned by TrackStateUtils.getTrackStateAtECal(track) to the cluster position as returned by cluster.getPosition() they are at very different z locations:

This had been fixed in git branch iss914, but was not merged into the master branch before that issue was closed.

The tracking code will have to be modified to reference ECAL_FACE_ENGINEERING_RUNS when reconstructing data from 2015 and 2016.

Other variables in BeamlineConstants should be reviewed and updated as necessary for the 2019 and 2021 runs.
